Zachariadis, 27, purchased several vuvuzelas months ago for $6 apiece on a soccer Web site, with the intention of traveling to the World Cup. When the trip fell through, he decided to bring the sounds of soccer to Yankee Stadium.

Though hugely popular in South Africa, the horns — which can reach an excruciating 120 decibels — are now reviled by soccer fans around the world.

Fortunately for American sports fans, the plastic instruments of irritation are still only available online or in novelty shops. But that could change.

Even though the denizens of the bleachers are known for being loud using just their own voices, Zachariadis said he couldn’t resist trying them out at the Stadium.

“I hid them in my shorts to get into the stadium, and when I pulled out the horns, the whole place went nuts,” he said.

“Phillies fans would walk by and we would blow it in their ear,” he said. “They had a laugh — they knew we were playing with them.”

Zachariadis even gave one of his instruments to a fellow Bronx Bomber fan, who helped demonstrate its ear-splitting abilities.

After Mark Teixeira hit a home run in the bottom of the fifth, Zachariadis went wild on the horn, which sounds like a cross between an elephant and a donkey.

That’s when the security guard told him there’s no braying in baseball.

“I blew on it only five or six times — for big plays,” Zachariadis said.

Zachariadis finally agreed to leave the game in return for not having his horns seized.

“I have been tossed from that place hundreds of times. Many times I even deserved it,” he said. “But this was ridiculous.”

The Yankees did not return calls seeking comment.

The rules for fans, posted on the team’s Web site, say you can’t “blow horns and all other distracting noisemakers.”
